A fast CUDA / OpenCL miner for
SASEUL (SL) — the resource-chain PoW of
saseul.com (single SHA-256 over previous_blockhash + header + nonce).
Features- Linux x86_64, HiveOS (custom miner package, NVIDIA and AMD rigs) and Windows x64
- NVIDIA Pascal … Blackwell (GTX 10xx – RTX 50xx), driver 525+ (on Windows only the driver is needed, no separate CUDA install)
- AMD Radeon: OpenCL, tuned for RDNA2, same binary picks the backend itself (--backend auto|cuda|amd); HiveOS detects AMD cards and runs mixed NVIDIA + AMD rigs
- Pools: Kavatar SL Pool (ours, the default), rabbitminer.cc, saseulmine.com, saseulpool.com, and solo on your own node via the bundled solo proxy
- Built-in GPU clock control (NVIDIA, per GPU): --lock-cclock, --lock-mclock, --coffset (undervolt), --moffset, --plimit — restored on exit and after a crash
- Every share is re-checked on the CPU before it is sent; a self-test against a real mainnet block runs at every start
- Colored console: accepted shares green, errors red, hashrate white, MH/W blue, temperature by threshold; a table every 60 s and your wallet as the pool sees it every 5 min (--color auto|always|never)
Kavatar SL Pool —
kavatar.kasplay.online- Stratum sl.kasplay.online:3333, login <SL address>.<worker>, no password
- PPLNS (2 × network difficulty), pool fee 2%, automatic payouts every 6 h from 10 SL, own SASEUL node
- Site: pool and network hashrate charts, wallet lookup (workers, credits, payouts), blocks; a ready HiveOS flight sheet for Import from Clipboard
Other pools- rabbitminer.cc — nl/fi.rabbitminer.cc:1931 (TCP), pool fee 10%, payout from 100 SL
- saseulmine.com — --pool saseulmine (HTTPS), daily payouts, vardiff
- saseulpool.com — --pool saseulpool (NATS), PPLNS 90 min, pool fee 5%, payouts every 6 h from 10 SL
- Solo — your own synced SASEUL node + bundled solo/sl_solo_proxy.py (MANUAL §8)
Measured hashrates (our rigs, ffgs 0.5.0)| Card | Settings | Hashrate | Power | Efficiency |
| RTX 3070 | 1400 / mem 810 / --coffset 325, Kavatar / saseulmine / solo | 5.05 GH/s | 74 W (board) | 68 MH/W |
| RTX 3070 | same, rabbitminer / saseulpool | 4.65 GH/s | 73 W | ~64 MH/W |
| RX 6800 XT | stock | 9.86 GH/s | 238 W (ASIC) | 41 MH/W |
| RX 6800 XT | 2300 MHz / 881 mV | 9.69 GH/s | 164 W (ASIC) | 59 MH/W |
Same RTX 3070 at a locked 1400 MHz on saseulmine.com with the pool's own miner 0.9.2.18: 2.51 GH/s at 87 W.
Every card differs — if "hardware error (bad candidate)" lines or rejects appear, lower the offset or the core clock. Memory clock does not matter for SL — lock it low.

--referrer <your address>. AMD undervolt values for the HiveOS OC profile (core, VDD, VDDCI, MVDD, SoC):
HIVEOS.md.
Fee: 2% = 1% dev + 1% referral (two 60 s windows every 100 min, the first after 15 min). The referral minute goes to
--referrer ADDRESS — whoever recommended ffgs to you.
Put your own mining wallet there and the total fee is 1% (the dev minute is then mined on Kavatar SL Pool). Without
--referrer both minutes go to the dev. Never mined on your own node.
